KF Three Segment Clamp 12 inch Heavy Duty Clamp Stainless Steel 304 Three Section Pipe Clamps

SS304 3-Segment Heavy Duty Clamp (12 Inch / 250A Korean Standard)

Secure your massive, large-diameter pipeline systems with the Aomite 3-Segment Heavy Duty Clamp.

Specifically engineered for 12-inch (250A Korean Standard) heavy-duty applications, this three-section bolted clamp ensures perfectly even pressure distribution around large ferrules, preventing leaks where standard two-hinge clamps fail. Forged from high-grade SS304 stainless steel, it is precisely machined to match a pipe outer diameter of 267 mm and a chuck (flange) outer diameter of 297 mm, featuring a special sealing groove size for maximum integrity. Whether you need this 250A model or other sizes, we maintain a massive stock supply ranging from 15A up to 300A to support your large-scale OEM projects.

Why use a 3-Segment Clamp for a 12-inch pipeline instead of a standard 2-segment clamp?

Pressure Distribution
On massive 12-inch (300mm+) connections, a standard two-segment hinge clamp cannot apply uniform pressure across the enormous circumference of the ferrule flange. A 3-segment design utilizes three separate interlocking steel sections and heavy-duty bolts to draw the clamp perfectly tight from all angles, ensuring a 100% leak-proof seal even under high fluid mass.
Installation Handling
A solid 12-inch steel clamp is incredibly heavy. A 3-segment bolted design allows engineers to easily position and assemble the clamp piece by piece around the massive pipe in tight spaces, rather than wrestling with a giant, stiff hinge.

What does "250A" mean in Korean Standard sanitary fittings?

Nominal Diameter (DN/A): In the KS (Korean Standard) and JIS (Japanese) systems, the "A" denotes the nominal size of the pipe. 250A corresponds roughly to a 10-inch or 12-inch system depending on the exact schedule.
Precise Matching: As specified in our actual measurements, an Aomite 250A clamp is engineered for a pipe outer diameter of exactly 267 mm and a chuck (flange) outer diameter of 297 mm. Always measure your existing ferrule with a caliper to ensure a perfect match.
